Quick Answer: What replaced TS-873A-8G-US?
Discontinued: TS-873A-8G-US | Replacement: TS-873A-SW5T-US
Why QNAP INC Discontinued the TS-873A-8G-US
The QNAP INC TS-873A-8G-US is fully discontinued and is no longer available for purchase. Based on the available research, QNAP has not published a detailed technical or business explanation for ending the TS-873A-8G-US. There is also no announced end-of-life date tied to the TS-873A-8G-US in the sources reviewed.
What is clearly confirmed is the product status: the TS-873A-8G-US appears on end-of-life listings and buyers are directed to the replacement model, TS-873A-SW5T-US. For procurement teams, that means the practical path forward is not to wait for new inventory of TS-873A-8G-US, but to evaluate and source TS-873A-SW5T-US instead.
In short, the reason available to buyers is straightforward: the TS-873A-8G-US is no longer for sale, and QNAP INC has positioned TS-873A-SW5T-US as the replacement part. Since no formal EOL timeline or broader announcement has been provided, IT teams should treat TS-873A-8G-US as unavailable and plan around TS-873A-SW5T-US for new purchases and refresh projects.
What's New in the TS-873A-SW5T-US
If you were previously sourcing TS-873A-8G-US, the replacement TS-873A-SW5T-US is the key model to review. Based on the available product research, the main updates center on processor visibility, networking capability, and platform expandability.
Processor
For TS-873A-SW5T-US, the available data specifically identifies an AMD Ryzen V1000 series V1500B 4C/8T 2.2 GHz processor. For TS-873A-8G-US, the processor detail was not specified in the research results provided. For IT buyers, that means the replacement TS-873A-SW5T-US offers a clearly stated CPU reference point during evaluation, while the discontinued TS-873A-8G-US does not have the same processor detail confirmed in the source set.
Networking
The TS-873A-SW5T-US is described as having two 2.5GbE ports and being 10G-ready. In contrast, networking details for TS-873A-8G-US were not detailed in the research findings. For teams planning storage connectivity, that makes TS-873A-SW5T-US easier to position in environments where faster Ethernet and future 10GbE expansion matter.
Platform Expansion and Storage Features
Another notable difference is platform capability. The TS-873A-SW5T-US supports entry-level NVIDIA GPUs and includes two M.2 PCIe NVMe SSD slots for Qtier. For the TS-873A-8G-US, the research only noted that it appeared bundled with a switch in the QNAP store context, rather than providing equivalent expansion details. If your use case involves tiered storage or light GPU-assisted workloads, TS-873A-SW5T-US brings clearer feature visibility.
Replacement Positioning
From a lifecycle and sourcing standpoint, the biggest change is simply availability. TS-873A-8G-US is discontinued and cannot be purchased as a current product, while TS-873A-SW5T-US is the replacement buyers should use for quoting, procurement, and project planning. That alone makes TS-873A-SW5T-US the relevant part number for current deployments.

Upgrade Checklist
- Update internal part records. Replace TS-873A-8G-US with TS-873A-SW5T-US in procurement systems, quoting templates, and approved hardware lists.
- Confirm current project requirements. Review whether your environment needs the two 2.5GbE interfaces, 10G-ready capability, or the expansion options listed for TS-873A-SW5T-US.
- Check compatibility assumptions. If prior designs were built around TS-873A-8G-US, verify network planning, storage tiering expectations, and any GPU-related use case against the documented features of TS-873A-SW5T-US.
- Review deployment standards. If your organization standardizes on specific NAS, storage, or edge infrastructure profiles, make sure TS-873A-SW5T-US fits those standards before issuing a purchase order.
- Communicate the lifecycle change. Let engineering, operations, and procurement teams know that TS-873A-8G-US is fully discontinued so they do not spend time trying to source unavailable inventory.
- Source from an authorized reseller. Use the correct replacement part number, TS-873A-SW5T-US, when requesting pricing and availability to avoid confusion with the discontinued TS-873A-8G-US.
Bottom Line
The QNAP INC TS-873A-8G-US is fully discontinued, with no announced EOL date and no longer available for purchase. The confirmed replacement is TS-873A-SW5T-US, which adds clearly stated processor, networking, and expansion details in the available research. For buyers still searching for TS-873A-8G-US, the right next step is to transition purchasing and planning to TS-873A-SW5T-US.
